The Elements of a Predictive Maintenance Solution from RFMicron

RFMicron offers a range of temperature sensors using our Smart Passive Sensing™ technology that can be used for continuous monitoring on electric motors and other industrial equipment.

RFM3250 Rugged Wireless Temperature Sensor

RFM3250 sensor

The RFM3250 is a rugged on-metal sensor that is appropriate for use on electric motors and windings, heating and cooling equipment, generators, and other equipment. It is small enough to fit in hard-to-reach spaces.

The RFM3254 is an even smaller version of the RFM3250, allowing placement in the tightest spots.
